On a logarithmic scale, a change between two values is perceived on the basis of the ratio of the two values.

Super-heavy element. The more protons an atom has, the higher its number on the periodic table. And with 115 protons, this new element earns the moniker super-heavy element.. For the sake of comparison, an atom of lead only has 82 protons.Gold has just 79.But you won't find a chunk of element 115 lying around anywhere.he newly formed element vanished quickly in a flash of radiation that scientists could measure. That flash, or fingerprint, confirmed the existence of an element with 115 protons at its center. That would give it the atomic number of 115 on the periodic table, the list of all elements known to humanity.
